Hi all,

i was doing a post vs pre contrast by averaging all the conditions and contrasting 3 (post 1, post2, pre2)of them vs 1 (pre1), as below. did i set correctly the contrast? should i balance or it is automaticcally balanced?? i have almost finished the project but and i got this doubt this doubt :-(.

Second question, how to weight the post sessions? i want to see connectivity changes over time

thank you a lot
